BACKGROUND OF THE INVENTION

The present invention relates to novel compounds, to pharmaceuticalcompositions comprising the compounds, to processes for making thecompounds and to the use of the compounds in therapy. More particularly,it relates to pyrrolidinyl urea and pyrrolidinyl thiourea compoundswhich exhibit TrkA kinase inhibition, and which are useful in thetreatment of pain, cancer, inflammation, neurodegenerative diseases andcertain infectious diseases.

The current treatment regimens for pain conditions utilize severalclasses of compounds. The opioids (such as morphine) have severaldrawbacks including emetic, constipatory and negative respiratoryeffects, as well as the potential for addictions. Non-steroidalanti-inflammatory analgesics (NSAIDs, such as COX-1 or COX-2 types) alsohave drawbacks including insufficient efficacy in treating severe pain.In addition, COX-1 inhibitors can cause ulcers of the mucosa.Accordingly, there is a continuing need for new and more effectivetreatments for the relief of pain, especially chronic pain.

Trk's are the high affinity receptor tyrosine kinases activated by agroup of soluble growth factors called neurotrophins (NT). The Trkreceptor family has three members: TrkA, TrkB and TrkC. Among theneurotrophins are (i) nerve growth factor (NGF) which activates TrkA,(ii) brain-derived neurotrophic factor (BDNF) and NT-4/5 which activateTrkB and (iii) NT3 which activates TrkC. Trk's are widely expressed inneuronal tissue and are implicated in the maintenance, signaling andsurvival of neuronal cells (Patapoutian, A. et al., Current Opinion inNeurobiology, 2001, 11, 272-280).

Inhibitors of the Trk/neurotrophin pathway have been demonstrated to beeffective in numerous pre-clinical animal models of pain. For example,antagonistic NGF and TrkA antibodies such as RN-624 have been shown tobe efficacious in inflammatory and neuropathic pain animal models(Woolf, C. J. et al. (1994) Neuroscience 62, 327-331; Zahn, P. K. et al.(2004) J. Pain 5, 157-163; McMahon, S. B. et al., (1995) Nat. Med. 1,774-780; Ma, Q. P. and Woolf, C. J. (1997) NeuroReport 8, 807-810;Shelton, D. L. et al. (2005) Pain 116, 8-16; Delafoy, L. et al. (2003)Pain 105, 489-497; Lamb, K. et al. (2003) Neurogastroenterol. Motil. 15,355-361; Jaggar, S. I. et al. (1999) Br. J. Anaesth. 83, 442-448) andneuropathic pain animal models (Ramer, M. S. and Bisby, M. A. (1999)Eur. J. Neurosci. 11, 837-846; Ro, L. S. et al. (1999); Herzberg, U. etal., Pain 79, 265-274 (1997) Neuroreport 8, 1613-1618; Theodosiou, M. etal. (1999) Pain 81, 245-255; Li, L. et al. (2003) Mol. Cell. Neurosci.23, 232-250; Gwak, Y. S. et al. (2003) Neurosci. Lett. 336, 117-120).

It has also been shown that NGF secreted by tumor cells and tumorinvading macrophages directly stimulates TrkA located on peripheral painfibers. Using various tumor models in both mice and rats, it wasdemonstrated that neutralizing NGF with a monoclonal antibody inhibitscancer related pain to a degree similar or superior to the highesttolerated dose of morphine. Because TrkA kinase may serve as a mediatorof NGF driven biological responses, inhibitors of TrkA and/or other Trkkinases may provide an effective treatment for chronic pain states.

Recent literature has also shown that overexpression, activation,amplification and/or mutation of Trk kinases are associated with manycancers including neuroblastoma (Brodeur, G. M., Nat. Rev. Cancer 2003,3, 203-216), ovarian (Davidson. B., et al., Clin. Cancer Res. 2003, 9,2248-2259), colorectal cancer (Bardelli, A., Science 2003, 300, 949),melanoma (Truzzi, F., et al., Dermato-Endocrinology 2008, 3 (1), pp.32-36), head and neck cancer (Yilmaz, T., et al., Cancer Biology andTherapy 2010, 10 (6), pp. 644-653), gastric carcinoma (Du, J. et al.,World Journal of Gastroenterology 2003, 9 (7), pp. 1431-1434), lungcarcinoma (Ricci A., et al., American Journal of Respiratory Cell andMolecular Biology 25 (4), pp. 439-446), breast cancer (Jin, W., et al.,Carcinogenesis 2010, 31 (11), pp. 1939-1947), Glioblastoma (Wadhwa, S.,et al., Journal of Biosciences 2003, 28 (2), pp. 181-188),medulloblastoma (Gruber-Olipitz, M., et al., Journal of ProteomeResearch 2008, 7 (5), pp. 1932-1944), secratory breast cancer (Euthus,D. M., et al., Cancer Cell 2002, 2 (5), pp. 347-348), salivary glandcancer (Li, Y.-G., et al., Chinese Journal of Cancer Prevention andTreatment 2009, 16 (6), pp. 428-430), papillary thyroid carcinoma(Greco, A., et al., Molecular and Cellular Endocrinology 2010, 321 (1),pp. 44-49) and adult myeloid leukemia (Eguchi, M., et al., Blood 1999,93 (4), pp. 1355-1363). In preclinical models of cancer, non-selectivesmall molecule inhibitors of Trk A, B and C were efficacious in bothinhibiting tumor growth and stopping tumor metastasis (Nakagawara, A.(2001) Cancer Letters 169:107-114; Meyer, J. et al. (2007) Leukemia,1-10; Pierottia, M. A. and Greco A., (2006) Cancer Letters 232:90-98;Eric Adriaenssens, E., et al. Cancer Res (2008) 68:(2) 346-351).

In addition, inhibition of the neurotrophin/Trk pathway has been shownto be effective in treatment of pre-clinical models of inflammatorydiseases with NGF antibodies or non-selective small molecule inhibitorsof Trk A. For example, inhibition of the neurotrophin/Trk pathway hasbeen implicated in preclinical models of inflammatory lung diseasesincluding asthma (Freund-Michel, V; Frossard, N., Pharmacology &Therapeutics (2008) 117(1), 52-76), interstitial cystitis (Hu Vivian Y;et. al. The Journal of Urology (2005), 173(3), 1016-21), inflammatorybowel diseases including ulcerative colitis and Crohn's disease (DiMola, F. F, et. al., Gut (2000) 46(5), 670-678) and Inflammatory SkinDiseases Such as Atopic Dermatitis (Dou, Y.-C., et. al. Archives ofDermatological Research (2006) 298(1), 31-37), eczema and psoriasis(Raychaudhuri, S. P., et al., J. Investigative Dermatology (2004)122(3), 812-819).

The TrkA receptor is also thought to be critical to the disease processin the infection of the parasitic infection of Trypanosoma cruzi (Chagasdisease) in human hosts (de Melo-Jorge, M. et al., Cell Host & Microbe(2007) 1(4), 251-261).

Trk inhibitors may also find use in treating disease related to animbalance of the regulation of bone remodeling, such as osteoporosis,rheumatoid arthritis, and bone metastases. Bone metastases are afrequent complication of cancer, occurring in up to 70 percent ofpatients with advanced breast or prostate cancer and in approximately 15to 30 percent of patients with carcinoma of the lung, colon, stomach,bladder, uterus, rectum, thyroid, or kidney. Osteolytic metastases cancause severe pain, pathologic fractures, life-threatening hypercalcemia,spinal cord compression, and other nerve-compression syndromes. Forthese reasons, bone metastasis is a serious and costly complication ofcancer. Therefore, agents that can induce apoptosis of proliferatingosteoblasts would be highly advantageous. Expression of TrkA receptorshas been observed in the bone forming area in mouse models of bonefracture (K. Asaumi, et al., Bone (2000) 26(6) 625-633). In addition,localization of NGF was observed in almost all bone forming cells (K.Asaumi, et al.). Recently, it was demonstrated that a Trk inhibitorinhibits the tyrosine signaling activated by neurotrophins binding toall three of the Trk receptors in human hFOB osteoblasts (J. Pinski, etal., (2002) 62, 986-989). These data support the rationale for the useof Trk inhibitors for the treatment of bone remodeling diseases, such asbone metastases in cancer patients.

Several classes of small molecule inhibitors of Trk kinases said to beuseful for treating pain or cancer are known (Expert Opin. Ther. Patents(2009) 19(3), 305-319).
